In one of my previous posts I described how to manually update NOD32 antivirus without an internet connection or using another computer . But for a non-tech person it is bit difficult to follow. Many readers email me about this. For such readers here is a tool for updating Nod32 Antivirus and ESET Smart Security (v.3.0 and v.4.0). This tool will automatically find your %SystemDrive% and create the correct folder, put the latest updated virus definitions and module files in it.
The program is portable and includes all latest virus signature files and modules. No need to download definitions from the server.
